Patented nee. ze, 1933 UNITI-:D SA'IIMES Ford Company, Wyan tion of Michigan .5 Claims.

My inventionrelates to improvements in detergent vdispensers for washing machines. It relates to that type ofdetergent dispenser which comprises a container for detergent which is so I' constructed that when arranged within the shower or falling stream of water in the washing machine the device functions to deliver a charge of detergent to the wash ,water during theoperation of the machine. A My improved device is so constructed that it not only functions continuously during the functioning of the machine but it operates to-discharge a constant quantity` of detergent during the time the machine is functioning.

A meritorious feature of my invention is that through the useof it` one is able to charge the dips'enser with a limited quantity of detergent and this detergent material -will be delivered at a uniforn rate to the wash water in the machine l0 regardless of the character of functioning of the machine and so long as the machine continues i tofunction. l

Another advantage is that the detergent container is constantly charged with a supply of 3.5 water and detergent which will maintain a 1miform functioningthereof regardless of iiuctuations in the functioning of the machine. Fur thermore, it is possible to charger the container before the machine begins to function so that l0 a limited amount of detergent maybe delivered to the wash water in the machine before the functioning of the machine begins, and this funchoning of the dispensing deviee win be eontmud by virtue of the functioning of the. machine. l5M Other advantages and meritorious features of my invention will more fully appear from the following description, appended claims, and accompanyingdrawing wherein Y Fig. 1 is a sectional view through any conveni0. tional type of washing machine showing my dis- 'penser in place therein, i l

Fig. 2 is a cross sectional view through the dispensing device' itself, and Fig. 3 is a view'taken on line 3--3 of Fig. 2. i5; In the figures of the drawing a washing machine 'of any well known type is indicated in Fig.V 1 as having a vat 10 within which the wash water is contained. A'screen '12 superimposes the vat I to collect foul material and prevent it from falli0 ing into the wash water. Screen trays or supports 14 are provided to carry the articles to be washed, such as the dishes shown in the illustra-` tion. Suitable pumping mechanism 16 is employed which delivers the wash water through Pz the spray pipes 1s end zo which function te direct m1112121 OFFICE DETEBGENT DISPENSER FOR` WASHING MACHINES Julius Barsky, Chicago, lll., assignor to The J.

a spray of water upwardly and downwardly, respectively, upon the dishes carriedrby the tray or rack 14. This v iew might be considered as showing the washing end of a large dish washing machine which also includes suitable rinsing 60 chambers and apparatus ot here shown.

In order to supply the wash water with the required quantity of cleansing or detergent ma.- terial I provide the detergent dispenser indicated generally as 22. This dispenser is shown more in Q5 detail in Figs. 2 vand 3. It comprises al container portion 24. This container has a Vnormally open top. A water collecting pan or cover 26 is provided.Y This cover has a flange 28 that seats over the top edge of the container so that the pan 70 portion of the cover hangs down into the container as shown in-Fig. 2. A screen or strainer 30 is provided which surmounts the cover 26 engaging over the flange 28 thereof and servesto prevent certain of the foul material-in the wash I6 water from falling into .the 4pan and clogging the discharge vent thereof.

The pan is provided with a water discharge 'pipe' 32 that depends into the container and terminates at a point in proximity to the bottom of the container as shown in Fig. 2. This discharge Vpipe also'extends upwardly above the bottom of the pan and is provided with a' water passageway 34 extending therethrough and terminating in the pan in a side opening 36 adjacent to the bottom of the pan. A needle valve 38 extends downwardly through the end of the pipe 32 Vand is adjustable to control the amount of water permitted to discharge through the pipe 32. 40 indicates a thumb lock nut.

The container itself is provided with adischarge outlet fordetergent in the form of a tubular portion 42 that forms an extension o`f vthe bottom of the container and terminates in proximity to the bottom of the pan 26 as indicated in Fig. 2. 'I'he container is filled with detergent 44 to about the line lindicated in Fig. 2.

In the operation of the device the dispenser is positioned within the `washing machine so as to be within the shower of water discharged by the machine and thiswater collects in the pan 26. .The valve 38 is so regulated that a very small amount of water will be permitted to ow through the drainV pipe 32 into the container. The amount of water permitted to flow through will, of course. depend upon the size of the washing machine, the amount of water, and the requirements for the particular washing operation, but it may be adjusted to meet any need. The water which isdischarged through pipe 110 32 enters the container in proximity to the bottom and seeps up through the detergent material. This liquid carrying detergent and solution rises in the lower part of the container until it overflows into the outlet pipe 42 and passes therefrom into the washing machine vat as indicated in Fig. 1. It will be apparent that once the detergent begins to function it will continue to function so long as Water is being discharged into the pan 26 and at a rate determined by the controlled flow of water from such pan into the container. It is likewise apparent that this pan may be charged with water when the dispenser is positioned in the washing machine so that a flow may begin prior to the commencement of the operation of washing.

I claim:
